SHIELD FOR SKYLIGHT Am) FLOOR-LIGHT oons'rrnno'rron.

I 5 Application filed July 20, 1927. Serial No.'-207,0 80.

My invention relates to anovel construction of a metallic shield orlenslholder adapted to receive lenses in Skylight and floorlightconstruction, wherein the shield or lens holder in which the glass lenssets has 7 its outer wall projecting below the bottom of the insideflange or gutter that sup orts a glass lens, the lower terminal of saiouter wall being deflected so asto form better anchoring means, which isembedded in the reinforced concrete. My novel construction of shield orlen holder enables a much greater body or greater area of cement to bearagainst the shield on its exterior surface, which I have found tobe agreat advantage in making the job more water-tight,:and my novelconstruction further results in the shield or lens holder-being moreeffectively anchored within the concrete;

To the above ends, my invention consists of a novelconstruction'ofmetallic shieldor lens holder which may be of polygonal or other shapeand is provided with an inwardly deflected flange or gutter upon whichthe lens is supported, the outer surface or wall of said shield beingcontinued downwardly below said inwardly deflected gutter, and providedwith a deflected terminal lip, whereby the shield is more firmlyanchored in the concrete and a more water-tight job is produced. WVhilemy novel construction of shield is adapted to a lens or glass of anysuitable construction, I preferably employ in conjunction therewith, alens of annealed glass or annealed wired glass.

By my novel construction, I amenabled to produce a floorlight andskylight construction, wherein the durability of the resultantconstruction is materially increased and atless cost.

For the purpose of illustrating my invention, I have shown in theaccompanying drawings one form thereof which is at present preferred byme, since the same has been found in practice to give satisfactory andreliable result-s, although it is to be understood that the variousinstrumentalities of which my invention consists can be variouslyarranged and organized and that my invention is not limited to theprecise arrangement and organization of the instrumentalities as hereinshown anddescribed.

Figure 1, represents a perspective View of a novel shield or lensholder, embodying my invention. a

' Figure 2, represents a plan view of a skylight and fioorlightconstruction, showing one manner of utilizing my novel shield.

Figure 3, represents a section on line 33 1. I V i Similar numerals ofreference, indicate corresponding parts,

Referring to the drawings: I

1 designates my novel construction of metallic lens holder or shield,the same comprising the vertical upright walls 2, which are preferablyfour in number when the shield is made in the form ofa rectangle, asshown, although it will be apparent that said shield maybe of otherpolygonal contour or 1 round without departing from the spirit of myinvention.

3 designates an inwardly projecting upwardly inclined lip, flange orgutter upon which a lens 4 is supported, said lens'being preferably ofannealed glass or of annealed wired glass having the wire mesh 5therein, if desired, as seen in Figs. 2 and 3. The vertical wallor outersurface 2 of the shield is continued downwardly, as indicated at 6,below the plane of the inner gutter or flange 3 and preferablyterminates in the outward- .ly deflecting upwardly inclined flangeor'lip 7, which, whenthe concrete 8 is set, is anchored therein as isevident, said lip extending completely around the shield.

It will be apparent that by the continuation or prolongation of theouter vertical surface or wall 2 to the extent indicated at 6, Iainenabled to have a greater body or area of cement contact against theshield on the outside, which I have found in practice to'be ofgreatadvantage in making the job more water-tight and in effecting theanchoring of the shield within the concrete. The edges of the lens 4:may be provided with a sealing or coating compound as shown in my priorPatent No. 1,587,487 if desired.

It will be understood that my novel construction of shield may beemployed with a glass or glass lenses of any character but I preferablyemploy lenses made-of annealed glass or annealed wired glass as I havefound that lenses of this character give efiicient and superior results.a

As will be understood from Figure 3, it will be seen that the concrete 8is continued around the gutter'3 up to the points 9, so

that the concrete entirely encloses all metal parts so that no corrosionthereof can take place which is an important deslderatum in structuresof this character, and in addition 1 a plurality of anchoring elements 3and 7 are provided, as is evident. V c

It will now be apparent thatl have vde-v vised a novel and usefulconstruction which embodies the features of advantage enumerated asdesirable in the statement of the'inventi'on and the above descriptionand while I have in the present instance shown and described thepreferred embodiment thereof which has been found in practice to givesatisfactory and. reliable results, it is to be understoodthat thesameis susceptible of modification in various particulars Withoutdeparting from the spirit orscope of the .invention or sacrificing anyof its advantages.

Having thus described my invention what Iclaim as. new and desire tosecure by LettersPatent, is: a

In a device of the character stated, a lens "holder comprising anoutervertical Wall forming a shield and an internal inwardly projectinggutter adapted to support a lens, said outer wallbeing continued belowthe plane of said gutter and being 'rearwardly and [upwardly deflectedat its bottom terininal'to-form anchoring means and a body of concretecompletely enclosing said anchoring means, shield and the underside ofsaid gutter, whereby said shield, anchoring means I and gutter areprevented from corrosion.
